Iowa, have invented entrain new uilil Liselul .1 r Improvements innh-I-leatvrs, oi which the following is a specification.

My invention relates to unprovements in tank-heaters, and pertainsparticularly to '10 that classlmown as portable heaters.

- The Object of my invention is to provide a' heater.ofthis'characterwhich is placed withother the fsameis full or whether there isbut'asmall amount of water in the tank.

Another'object of my invention is to pro vide a heater of this characterin which there is less liability of the gasolene-tank becoming heatedand exploding and also to more thoroughly heat and cause the circulationof the water within the tank.

In the accompanying drawings, Figure 1 is a perspective view of thetank, partly broken away and my improved heater placed therein. Fig. 2is a longitudinal vertical section of'my improved heater, taken on line:1: a: of Fi 3. tio nal View taken on line y y of Fig. 2.

Referring now to the drawings, A represents the tank, the ordinarystructure to which I desire to apply my improved heater, althou h thesame may be applied to any form oi tank.

B represents my improved heater, which, asshown', is in the form of anoblon boxlike member and is preferably made 0 sheet metal and perfectlywater-tight, so that it may rest within the tank of water. The up (Emilyheat the water within the tank is covered with two covers C C, leavingan openspace D between the same. These covers are rovided with handles FF, by means of Whic they may be readily removed. The

cover C, as shown, is considerably larger than the cover C, thuscovering the greater portion of my improved heater or that portion inwhich the burner is located. The cover C" covers that portion of theheater in which the gasolenetank is located.

The space D between the covers C C extends, as clearly shown, transverseof the heater and through which the air is fed to the burner. Fittingwithin this s ace is a slidedraft G, which projects a sight distanceabove the upper end of the heater and is pro thehnrncr.

Flg. 3 is a transverse vertical sec- I end of said heater is open, asshown, and

f vidml with open side '9, through which the 1 air passes. The saidslide-draft is of a boxlike form and ex: curls down within the heaterand rrsts upon the bottom thereof. thus dix'iding t'lidheat cr lIllOtlub1wncr-clunnhrr H and the tanlechamber I. The side (i at its lowerend is cutaway hi q'yand thusallowing the air to "pass from 4'burner-comp" a acenft and lgelow de draft, *as shown, dividing the heate two distinct compartments, with li ofcold air at all times passingbrin s-n the two compartments, prevents the compar'uncnt i from becomingat all heated.

The side (i of the slide-draft G is provided wiih a rearwardly-exrending portion J, which is adapted to support the vertically-disposedpartition K intermediate the ends of thee-oinpartment I. This partitionsupports this oiltank L at. a point about the center of thecoinpartinent I, and thus the oil therein is revented from becomingheated at any time. The said tank L is rovided with a downwardly andforwar y extending ipe L, which passes through the slide-dra G and endsat a point about midway of the compartment H. Pivotally carried by theouter end of the pipe L is a burner M, which is of the ordinary type,and the pivotal connection of the burner with the pipe allows the burnerto be swung around, the urpose of which will be hereinafter described\Vithin the compartment H, above the burner M, is supported aheat-containing hood X, which is of a rectangular inverted box-likeform. The said hood is supported by the brackets 72, which extendupwardly and outwardly and are secured to the side of the heater B. Thisdiaphragm is adapted to concentrate and hold the heat therein, thushearing the coil 0. The said coil 0 is made of three-quarter inch tubingand of a V- shaped form, with the coils about one-quarter of an inchapart, the ends of said coil extending through {he diaphragm and passingout through the end of the heater. These ends 0 0 are luI'Il'Qddownwardly and extend within an inch or two of the bottom of the heaterand at the outside thereof. By this arrangementof the coil and thedownwardlyextending ends thereof it will be readily seen that a thoroughcirculation of the water is caused Within the tank, no matter how muchwater may be therein. The coil may be arranged within the hood on aslight inclinae slide-drafninto the through the coil.

tion, so that should the water within the tank be consumed and the fireextinguished the water will drain from the coil and prevent the freezingup of the coil. The burner, as heretofore described, is ivotallyconnected to the pipe L, and thus a lows the same to be swung aroundfrom under the coil for the purpose of cleaning and repairing.

The cover 0 of the compartment H is rovided with a ventilator P, whichallows o the escape of the products of combustion, preventing theheating of the casing B, as the heating of the water within the tank isnot reliedthereon by the same, but is accomplished by the circulation ofthe water The cover is also provided with openings Q, which are coveredwith glass, whereby the burner can be readily seen without removii'igthe cover.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A tank-heater comprising a receptacle, a draft arrangement of abox-like form dividing the receptacle into two distinct compart ments, atank within one of said compartments, a pipe leading from the tankthrough the draft arrangement and into the other compartment, a burnerpivotally mounted upon said ipe, ahood above said pipe, a coil beneath te hood and having its ends extending out through one side of thecompartment, the end of said pipe turned downwardly, a removable coverabove the compartment carrying the burner and provided with aventilator, and a removable cover for the compartment carryingthe tank.

A tankheater comprisin a receptacle, an oil-tank within one end, aburner within the opposite end and in communication with the oil-tank, adraft arrangement of a width cciual to that of the heater intermediatethe 0i -tank and burner and completely dividing the rece tacle into twodistinct compartnients a ood above the burner, a coiled pipe within thehood and extending out through one side of the receptacle, and the endsof the said pipe on the outside of the receptacle turned downwardlynearly to the bottom of the receptacle.

In testimony whereof I aflix my signature in presence of two witnesses.
